IMPROVEMENT IN MACHINES FOR MAKING BARREL-HEAD-S.

Specification forming part of Letters Patent No. 209,311, dated October22, 1878; application led September 25, 1878.

To all whom it may concern:

Beit known that I, ABRAHAM WAsoN, of New Boston, in the county ofHillsborough and State of New Hampshire, have invented certain new anduseful Improvements in Machines for Cutting and Shaping Barrel-Heads, ofwhich the following is a specification:

This invention relates to an improved machine for cutting and shapingbarrel-heads, and it has for its object to provide an apparatus in whichthe heads may be automatiwhich it may be caused to approach to or recede from the other, which is lixed, in order to automatically seize theblank and hold it during the operation of the cutters, and' release thehead when completed, as more fully hereinafter specified.

My invention also consists in the combination, with the clamps androtary cutter-heads, of a guide for directing the insertion of theblank, and automatically-working stopping devices for holding the blankuntil the preceding head has been cut and discharged from between theclamps, as more fully hereinafter speciied.

My invention further consists in the combination, with the clamps, of anautomaticallyoperating releasing device, for releasing the qfinishedhead from the clamps, as more fully hereinafter set forth.

In the drawings, Figure 1 represents a front elevation of my improvedapparatus. Fig.,2 represents a rear elevation, and Fig. 3 represents atop view, of the apparatus.

The letterA represents the frame of the machine, which carries theworkin g parts thereof. The letter B represents two clamping-disks,

and mounted upon cylindrical bars C G1, eX

tending through the hollow shafts D of the cutter-heads DI, which arejournaled in bearings E in the frame A. The hollow shafts are eachprovided with a pulley or drum, F, by which a rotary motion may beimparted to the same; and the cutter-heads each carry an angular cutter,G, by means of which the barrelhead is cut from the blank and chamferedat its edges.

At the rear of the pulleys, on the hollow shaft of each cutter-head, aresecured collars H, which are embraced by the branches K at the ends ofthe bifurcated levers L, fulcrumed to the frame A, the opposite ends ofsaid leshafts. Each of said levers is provided with an extension, T,rising vertically, and then extending horizontally to the center of theframe, where they terminate in bifurcated branches A. The saidextensions move to and from each other when the machine is in operation,and form a stop for regulating the insertion of the blank, as more fullyhereinafter specified.

The letter B represents the guiding devices,

' which consist of upright standards rising from the frame of theapparatus above the clamps and the stops, a space being left between thetwo for the insertion of the blank to be fed into the machine.

The levers S and Sl are provided at their outer ends withfriction-rollers C2, whichfsit in cam-grooves D2 in the drums L on theshaft P, by which the levers are given an oscillating movement.` Thelever Sl serves to reciprocate the bar C1 of the clamp, so as to causethe same to approach and recede from the opposite clamp at properintervals to seize the blank and subject it to the action of theeutters. Said lever also serves to actuate the extension T1 of the stop,the other lever, S, serving to actuate the opposite extension, so as tooperate in unison therewith, and riding free of the clamping-disk bar C,which is stationary.

To the lever S is secured one end of a lever, G', fulcriuned to theframe A, the other end of which is pivoted to a cross-bar, H', to whichare attached the reciprocating rods K', mounted in ways or guides L" inthe frame, and to which are attached the upwardly-extending arms, M',which sit just behind the stationary clamp, and serve, when thrustforward to force the finished head away from the stationary clamp, tofacilitate the discharge of said head from the machine.

The shaft P is provided at one end with a gear-wheel, P', which engagesa pinion on a shaft, R', journaled at one end of the machine,

said pinion being provided on its front face with a ratchet, S2, andbeing capable of a longitudinal movement on its shaft, controlled by alever, T2, by means of which it can be thrown into and out of gear witha similar ratchetwheel on the hub of a loose pulley, U2, mounted on thesame shaft, whereby the shaft may be putin motion or stopped at will.

The operation of my improved apparatus is as follows: The hollow shaftsof the cutterheads being put in motion, as well as the shaft I), thereciprocating clamp will be caused to travel back and forth toward thestationary clamp. At the same time the stopping devices will be causedto approach to and recede from each other, and the cutter-heads willalso be caused to approach to and recede from the work. The work is fedin between the guides, and is held by the stops, which close together atthe proper time, until the reciprocating head has receded from'thestationary head and the two clamps arein position to receive the blank.When in this position the stops have receded from each other, permittingthe blank to be fed in between the clamps, by which it is seized whenthe cutters advance andcommence their work upon the blank. When the headis cut and severed therefrom the parts again assume their normalpositions, ready for work upon the succeeding part of the blank.

What I claim is- 1. In a machine for making barrel-heads, thecombination, with the clamping-disks B, their shafts C (ll, thecutter-heads D', and their hollow shafts D, of the collars H onthelatter, the pivoted levers K, attached to said collars, and the drumsOonthe shaftP,havingcam-grooves, in which the ends of the levers K arearranged, substantially as and for the purpose described.

2. The combination of the following element-s, to wit: theclamping-disks B B, their shafts C C', the cutter-heads D, their hollowshafts D, and mechanism for reciprocating the same, the pivoted lever S,pivoted to one of the clamp-shafts, and the drum L', having acam-groove, in which the end of the lever S is arranged, substantiallyas and for the purpose described.

3. The combination, with the stationary clamping-disk and its shaft, of.the Vertical releasing bars M', the rods K', cross-bar H', verticalpivoted lever G', and a horizontal lever, S, attached at one end to thelever G', and having its other end arranged in a cam-groove in therotating drum L', all arranged to automatically move the bar M' todischarge the finished barrel-head, substantially as shown anddescribed.

4.. The combination, with the clamping-disks B and rotary cutters Dl ofa machine for making barrel-heads, of the upright standards, formingguides B', facing each other and arranged above the disks and cutters,the bifurcated branches A', and mechanism such as described forautomatically reciprocating said branches, as and for the purposedescribed.

5. In combination with the stationary clamping-disk and the rotarycutter, the releasingbars, automatically operated by suitable mechanismto discharge the finished head, substantially as specified.

In testimony that I claim the foregoing I have hereunto set my hand inthe presence of the subscribing witnesses.

' ABRAHAM WASON.
